I suggested 30 secs wait. So you prefer Martin's suggestion?
Let's say, for argument's sake, two minutes.
Let's be clear about this; it was merely a suggestion for the sake of the argument.
Basically, the WC, based on their own speculative time line, had only about 11 minutes to get Oswald from the roominghouse to 10th and Patton to kill Tippit, which by itself was a tight squeeze. Mack's video proves that to some extend. So, any time spend waiting at a bus stop cuts into those critical 11 minutes which is why it needs to be reduced to a bare minimum and why it needs to be discussed.
